Mark Tyburski of Circle Organics joins us this week to answer the question: What is good soil?  Good soil composition is the foundation of any successful garden and Mark will be with us to talk about building a good soil ecosystem in your garden with the Biltmore Naturals Rose Care Kit.  This combination of nutrients for the garden is used at the magnificent Biltmore Estate & Gardens in Asheville, North Carolina. The estate is home to the Biltmore International Rose Trials and serves as a testing ground for roses in terms of disease resistance, vigor, bloom power and over all heath. Biltmore International Rose Trials Coordinator and author of the popular book "Everyday Roses" join us for a chat on the upcoming judging of the trials and also the role that good soil plays in the rose trial process.
